USB sticks

below you will find a list of "good" & "bad" USB-sticks - please fill in your experiments

There is a lot different USB-devices on the market, which difference both in what they identify as (USBClass), how they communicate with the desk (USB Subclass), and the filesystem format of the diskspace to write your data to.

The grandMA OS (VxWorks) is not a plug-n-play OS, so if stick needs special installer etc it may be unsupported.

If you are having issues with USB-sticks, please take the following precuations before dedicating a specific stick to use for the grandMA

• on your PC download and install USBDeview to confirm correct Class and Sublass

• Class should be 08 and Subclass 06 - If this is not the case, you might need to find another stick
• Still on your PC, Open "My Computer", Rightclick on USB device (stick) and select Format in the contextmenu
• select Filesystam FAT32 and "format disk" (data on stick will be lost)

-

• This is taken from MA-Share.net

"USB stick must be formatted as FAT32. There are various formatted sticks out there, and a suspicion that other FATs can course trouble or will not work at all."

• This is taken from the release notes of version 5.767E:

"Not supported Subclass 2(SFF8020I), which is normally used for CD/DVD devices.

Unfortunately there are such sticks at market.

Partly supported Subclass 5 (SFF8070I), not tested yet.

Full supported Subclass 6 (SCSI), which are most sticks and drives."
